(i \rightarrow b), (ii \rightarrow d), (iii \rightarrow a), (iv \rightarrow c)

(i) Halogen atom in alkyl halide is bonded to a carbon atom that is sp3 hybridised, where further addition of alkyl group may happen. CH_3-CH (X) - CH_3  is alkyl halide.

(ii) Halogen atom in allyl halide is bonded to a carbon atom next to C=C double bond that is sp^3 hybridised. CH_2= CH - CH_2- X is allyl halide.

(iii) Halogen atoms in aryl halide are bonded to a carbon atom that is sp^2 hybridised aromatic ring. C_6H_5X is aryl halide.

(iv) Halogen atoms in vinyl halide is bonded to a sp^2  hybridized carbon atom of a C=C double bond. CH_2=CH-X is vinyl halide.
